The NASA Double Asteroid Redirection Test (DART) mission will be the first space experiment to demonstrate asteroid deflection by a kinetic impactor. DART will impact Dimorphos, the secondary member of the (65803) Didymos system, in late September - early October 2022 in order to change the binary orbit. DART will carry to Didymos a 6U CubeSat called LICIACube, contributed by the Italian Space Agency, to document the DART impact on Dimorphos and to observe the impact ejecta. DART will use ground-based telescopes to determine the orbital period change caused by the impact on Dimorphous. Besides, the DART spacecraft observations consist of approach imaging to measure Didymos light curves to determine rotation and orbital characteristics, further approach imaging to measure the sizes and shapes of Didymos and Dimorphos, and terminal approach imaging to determine the impact site location and local surface geology. LICIACube will observe the structure and evolution of the DART impact ejecta plume and image the non-impact hemispheres of Didymos and Dimorphous. We will update DART status and discuss DART determinations of the momentum transfer efficiency and new modeling results of DART impact outcomes.

 

About Andy Cheng

Andy Cheng is Chief Scientist for planetary defense at JHU/APL and a Lead Investigator for the DART (Double Asteroid Redirection Test) mission, the first mission to demonstrate asteroid deflection by a kinetic impactor. He previously served as Deputy Chief Scientist for Space Science in NASA’s Science Mission Directorate, at NASA Headquarters, from 2007 to 2008. He was the Project Scientist of the NEAR mission, which was the first mission to orbit and land on an asteroid in 2001. He was the Orbital LIDAR scientist on the Joint Science Team for the JAXA Hayabusa mission to asteroid Itokawa in 2005. He was an Interdisciplinary Scientist on the Galileo mission to Jupiter from 1995 to 2003 and a Co-Investigator on the Cassini mission to Saturn. He was the Principal Investigator for the Long Range Reconnaissance Imager (LORRI) on the New Horizons mission which visited Pluto in 2015 and the Kuiper Belt Object Arrokoth in 2019. He joined the Applied Physics Laboratory in 1983, and he founded the Planetary Exploration Group there in 2004. He obtained his undergraduate degree in physics in 1971 from Princeton University and his Ph. D. in physics from Columbia University in 1977.
